Small Nodule: The infection usually starts with the development of a single painless nodule on the genitals or around the anus, although it occasionally appears on other parts of the body. The nodule soon breaks down into an ulcer, which enlarges and destroys the skin and subcutaneous grown. In the South Atlantic states V. rotundi-folia has been domesticated for Table grapes and for making wine.
Characterized by small nodule on stemlike part of abdomen which attaches it to thorax. Males and females have 2 pairs of long, delicately-veined wings which are lost immediately after mating. Strong biting mouthparts are tools used for all activities.
Can be house pests, but on whole are more beneficial than destructive
